Pixel accuracy (PA) is a basic evaluation method in image segmentation, that is the proportion of pixels that are classified correctly.
The mean pixel accuracy (MPA) is the improved methods of PA, which performs more objective [1]}.
Dice is applied to measure the inner similarity between segmented image and GT [2]}.
Intersection over union (IoU), also named Jaccard, is the proportion of intersection and union of the prediction and ground truth [3]}.
